Hello community. I have a problem with display witch connected through HDMI to a GW5404 board (GATEWORKS/Ventana) is based on i.MX6Q cpu.
I've installed Ubuntu 14.04 trusty-x11-ventana image with LXDE desktop environment. It looks pretty nice, but...
My display has frames witch cover a little area near edges of display matrix. I found some manners how to do it,
but they advise to use xrandr linux command. But problem in that xrandr gives the answer "Can`t open display".
I`ve checked once more xorg.conf content, and it is the same as in i.MX_Reference_Manual_Linux.pdf p.173.
How can i change display settings, and reduce display image?
And, why xrandr can`t find display?
Thanks in advance for all the help.
